Depending on how we look at a paragraph, the same words in the paragraph can mean something totally different if we have a different interpretation of them. I like how he explains that there are different meanings to different words used in a paragraph, because this will greatly affect how we paraphrase a specific section based on how we think it means. I don't understand how we can change people's thoughts though. Some people perceive life very differently from others. For example, some people just think a little more negatively, so if they read this specific word or section and try to paraphrase it, it will be much more different than if someone with a more positive attitude paraphrases it. So, how can we teach some people to paraphrase positively or negatively? I guess you can try to give both positive and negative opinions, but some people don't have anything positive or negative to say about a specific topic.
